Wellens' syndrome is an electrocardiographic manifestation of critical proximal left anterior descending (LAD) coronary artery stenosis in people with unstable angina. Originally thought of as two separate types, A and B, it is now considered an evolving wave form, initially of biphasic T wave inversions and later becoming symmetrical, often ...
Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. [2] Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility, numbness and tingling in the hands and feet. [1]
Women over the age of 50 with cervical cancer tend to have a higher risk of vaginal stenosis from radiation therapy. [10] Tobacco use is also associated with a higher risk of vaginal stenosis. [ 10 ] There is also a high correlation between vaginal stenosis and vaginal pallor reactions, which is when the mucous membranes thin and dry out ...
Snares and tapes are used to facilitate exposure. The aim is to avoid distal ischemia caused by blockage of the vessel supplying distal portions of the left ventricle, so usually LITA to LAD is the first to be anastomosed and others follow. For the anastomosis, a fine tube blowing humidified CO 2 keeps the surgical field clean of blood. Also, a ...
Women and those who are young may show abnormalities on their test even though no signs of coronary ischemia or CAD are present. [29] Harmless arrhythmias present at baseline may distort the results. [11] Diagnosis of coronary artery disease is missed in 37% of men and 18% of women with a negative test. [33]
Family history – First-degree relative diagnosed with atherosclerosis before age 60 or who had an ischemic stroke; The American Heart Association also recommends screening if a physician detects a carotid bruit, or murmur, over the carotid artery by listening through a stethoscope during a physical exam. For people with symptoms, the American ...
Furthermore, such tests give frequent false-positive results in individuals without any symptoms. [12] For example, some have suggested that anismus is an over-diagnosed condition, since the standard investigations or digital rectal examination and anorectal manometry were shown to cause paradoxical sphincter contraction in healthy controls ...
If untreated, severe symptomatic aortic stenosis carries a poor prognosis, with a 2-year mortality rate of 50-60% and a 3-year survival rate of less than 30%. [63] Prognosis after aortic valve replacement for people younger than 65 is about five years less than that of the general population; for people older than 65 it is about the same.
